But not to the top! Windows Forms apparently don't like having their title bars moved off the top of the screen. You can drag the form up, but it bounces back down again as soon as you release the mouse button.
I haven't used a Windows OS where that would happen. The closest I've come across so far is in Win7 if you're moving a window up and the cursor enters the top screen zone it'll suggest maximizing the form, but right here in WinXP (I'm at work) I can have a window with the title bar partially off the screen at the top there (only the bottom half of the close button is visible right now)
